With the experimental data of this porous liquefied DAC carbon dioxide trap, Xu Chuan returned to NTU.
In the office, he flipped through the data he had brought back and stared at the ceiling, lost in thought.
"Tang Ran."
After coming back to his senses, he shouted towards the assistant room outside.
Soon, assistant Lu Ling with a round face walked in: "Sister Ran went out ten minutes ago and hasn't come back yet. Professor, what can I do for you?"
Xu Chuan nodded and said, "Then help me contact the leaders of the city government and make an appointment with them."
"Okay, Professor." Lu Ling responded quickly, and then asked: "Is there any specific area of leadership or work?"
A municipal government, especially a metropolitan city at the sub-provincial level like Jinling, must have different responsibilities for different tasks, and it is naturally more efficient to be able to directly connect with leaders in corresponding fields.
Xu Chuan thought for a moment and said, "Industrial and environmental protection."
"Okay, Professor, are there any other jobs?"
Lu Ling glanced at Xu Chuan in surprise. The word environmental protection really surprised her. When did the professor start studying this?
"temporarily unavailable."
Xu Chuan waved his hand, his eyes fell on the experimental data on the table, and he pulled out a stack of manuscript paper from the drawer.
The porous liquefied DAC carbon dioxide trap, although the current purification speed is not very fast, can make up for the quality through quantity.
Especially in large cities with many high-rise buildings, theoretically, it is possible to expand the purification area by occupying the exterior walls of one floor or several floors.
He plans to conduct a pilot project to see if investing in the construction of a large number of porous liquefied DAC carbon dioxide capture devices in densely populated urban agglomerations can change the ecological climate of a large city.
Jinling is a good choice. Although the initial investment may be too high, Jinling has sufficient economic strength.
And for a city, especially a city like Jinling that is like a 'furnace' every summer, the investment to improve the temperature and make it more livable is undoubtedly worthwhile.
It is very simple. Cities are the result of population agglomeration and industrial agglomeration. The number of people determines the development of cities. The impact of a huge population is huge.
Not only will the economy become more developed, but also the development of industry, the amount of infrastructure, the richness of culture, sports and entertainment, the level of medical education and other aspects will have a great impact.
After the first batch of Daybreak fusion reactors were piloted in Jinling, the city's permanent population has exceeded 12 million, and it is still rising rapidly.
If Jinling can be made more livable, I believe the city government would be happy to see it and would be willing to spend the money.
But what Xu Chuan didn't expect was that he sent the invitation to the city government through his assistant at noon. Before four o'clock in the afternoon, the top leaders of the two major industrial and environmental departments in Jinling City hurried to Nanjing University.
.
Carrying a textbook and finishing a big class, he just rushed back to his office from the teaching building when he received a report from his assistant.
"Professor, the two directors of the Municipal Leadership Industrial Information Bureau and the Ecological Environment Bureau are here."
Hearing this, Xu Chuan was a little surprised: "So fast? Where are the people?"
Lu Ling quickly replied: "In the reception room."
Throwing the textbook on the desk, Xu Chuan asked casually: "How long have they been here?"
"About half an hour."
"Invite them over."
"Okay, Professor."
Lu Ling responded and walked out quickly.
After a while, two middle-aged and elderly men in suits and ties walked in quickly.
"I'm sorry to have kept the two leaders waiting for so long. I was teaching students just now." Seeing the two city leaders walking in, Xu Chuan stood up, greeted them with a smile, and said hello.
"In other words, Academician Xu, you are too polite. Teaching and educating people is the foundation of the country. We have just arrived not long ago."
The middle-aged man with a gold lace in the front laughed and walked up, extending his hands with enthusiasm: "Hello, Academician Xu, I am Han Zizhen, temporarily appointed as the director of Jinling City Industrial Information Bureau.
I heard that you invited us to discuss work, I hope you are not late."
Xu Chuan smiled and shook hands with Director Han, and then said hello to the Director of the Bureau of Ecology and Environment.
"Director Han, Director Li, please take a seat first."
He motioned to the sofa next to him, and Xu Chuan sat down with a smile.
After a few words of greeting, Lu Ling walked in with tea, poured a cup for everyone, and then quietly left, closing the door of the office.
After picking up the tea cup and taking a sip, Xu Chuan looked at the two directors and said, "I would like to trouble the two leaders to make a trip this time. The main reason is that I have a new technology on hand, or a new idea that I want to use."
Let’s do a pilot project here in Jinling City.”
When they heard about the new technology, the two directors' eyes lit up, and they quickly said: "Academician Xu, please tell me, if we at Jinling can help, we will do our best."
This new technology, don’t think too much about it, it must be great.
Smiling, Xu Chuan handed over the experimental data of the porous liquefied DAC carbon dioxide trap that had been prepared on the coffee table, and said:
"I didn't expect the city to be so efficient. I remember I sent a message through my assistant at noon, and you guys arrived in the afternoon."
"I haven't had time to prepare the relevant project plan yet, but I have a piece of experimental data here that you two can take a look at first."
Han Zizhen laughed, took the experimental report with both hands, and said with a smile: "Serving the people, this is what you should do."
On the side, Li Jian from the Bureau of Ecology and Environment came over. After taking a look at the information in the experiment report, he looked at Xu Chuan curiously and asked.
"Porous liquefied DAC carbon dioxide trap? What is it? Can you please explain it to us briefly, Academician Xu?"
"certainly."
Xu Chuan nodded and said with a smile: "To put it simply, it is a device that can adsorb and capture carbon dioxide from the air and convert it into oxygen, starch, glucose, gasoline, graphene and other materials."
"It uses a technology that combines ion exchange membrane and isophorone diamine, and is driven by electricity to capture carbon dioxide in the atmosphere. In air with a concentration of 400ppm, the ability to remove carbon dioxide in the atmosphere exceeds 99%!"
"It is more than twenty to fifty times that of ordinary carbon dioxide adsorption technologies or materials on the market. Even the best amine materials are only about one-fifth to one-tenth of it..."
Opposite the sofa, Han Zizhen's eyes suddenly lit up when she heard this introduction.
It absorbs and captures carbon dioxide and turns it into oxygen, starch, gasoline, graphene and other industrial products, turning waste into treasure. What a good thing.
If someone else had proposed these concepts, he, the director of the Industrial Information Bureau, might have considered questioning whether this technology could really be commercialized.
But for the person in front of me, there is absolutely no need to worry.
After thinking for a while, he quickly said: "In other words, this set of equipment can cooperate with the industrial system to process carbon dioxide emissions to the greatest extent."
Opposite the sofa, Xu Chuan nodded and said with a smile: "It is undeniable that the removal of carbon dioxide in the industrial system is indeed its value, and its efficiency will be higher than other carbon dioxide removal systems."
"But in my opinion, its greater value is not here, but in another direction."
Upon hearing this, the two leaders of Jinling City, Han Zizhen and Li Jian, both looked over with curiosity and interest.
"Another direction? Which way?"
Xu Chuan smiled, looked at Director Li of the Ecological Environment Bureau, and said: "I believe the two leaders also know very well that with the development of industrialization and the massive emission of carbon dioxide, after entering the 21st century, the greenhouse effect will
The impact is getting more and more serious.”
"Not to mention the various problems it brings about such as global warming, melting of polar glaciers, rising sea levels, etc. In cities alone, it can be said that it is getting hotter year by year, which is enough to make people miserable.
.”
"The porous liquefied DAC carbon dioxide trap may not necessarily be able to completely reverse the climate of the entire earth, but it can theoretically have a certain mitigating effect on the high concentration of carbon dioxide in cities."
"Although the high temperature in the city cannot be entirely attributed to greenhouse gases dominated by carbon dioxide, it is certain that when these greenhouse gases are significantly reduced, the temperature in the city will also decrease."
"In short, this system can play a big role in regulating the temperature in the city. At the same time, it can also produce a certain amount of oxygen, starch, light chain gasoline, glucose and other carbon compounds."
"And all that needs to be paid is some electricity that is now extremely cheap."
"This is currently on the market, even in the whole world, no country or company can do it."
Looking at the two people in front of him, Xu Chuan smiled and asked: "How about it? Is the Jinling City Government interested?"
Listening to Xu Chuan's explanation, Han Zizhen from the Industrial Information Bureau, who had already briefly reviewed the experimental data report in his hand, thought for a while and then cautiously asked:
"Although I don't know anything about the technical field, but if you want to change the carbon dioxide content of a city as a whole, I'm afraid the number of carbon dioxide adsorption devices that need to be deployed should be quite large, right?"
Xu Chuan nodded and said: "This is for sure. According to the current experimental data, if it wants to have a certain impact on the atmosphere of the entire Jinling City... I am afraid that most of the high-rise buildings in the city will have to be inspected.
Transformation.”
"Use at least one floor of these buildings or renovate the exterior areas of multi-storey buildings."
"Of course, this refers to non-residential communities, mainly those buildings with more than 30 floors in the city center."
Hearing this, Han Zizhen couldn't help but smile bitterly.
It would be easy to renovate the high-rise buildings in Jinling City if they were only those in the ultra-high commercial center. After all, there are currently only about 30 or 40 high-rise buildings over 200 meters in Jinling City.
But a building with about thirty floors is almost the backbone of a city.
Whether it is an ordinary commercial building or a residential building in a residential area, many are near or above this level.
Even if we put aside non-residential areas and just renovate commercial buildings, the amount of work is so huge that he cannot calculate it in a short time.
There are probably more than 500 30-story, 100-meter-long buildings in Jinling City currently.
Especially after the completion of controllable nuclear fusion technology, the Dawn Fusion Reactor was the first to be piloted in Jinling. In the past two or three years, a large number of super-high-rise buildings have been constructed.
Taking a deep breath, Han Zizhen asked: "Academician Xu, how much does this carbon dioxide adsorption and capture device cost approximately?"
Xu Chuan shook his head and said: "I really don't know much about this. But among the porous liquefied DAC carbon dioxide traps, the most expensive one is the material that adsorbs carbon dioxide inside. The other materials shouldn't be that expensive."
"As for the carbon dioxide adsorption material, that is, ion exchange membrane isophorone diamine, according to the current cost, it is probably close to 300 per kilogram."
"One kilogram of isophorone diamine can cover an adsorption area of about two square meters. Each square meter can treat about one hundred cubic meters of air in one hour."
"However, isophorone diamine is not disposable. It can recycle itself. Simply put, it can be used for a long time after being put in once. According to the current experimental data, it can probably run for almost ten years."
"The specific cost price will probably have to be calculated later."
Han Zizhen nodded and silently calculated in her mind.
Three hundred yuan per kilogram can be used to pave two square meters. Based on the area of a commercial building of 20,000 square meters, even if it is just to modify the exterior wall, the carbon dioxide absorption material alone will cost at least 300,000 yuan.
It may not sound like much, but it is just a ‘part’ in this set of equipment, and only one floor of a building has been renovated.
If there are 500 buildings in Jinling City that are more than 100 meters tall, that is, more than 30 floors, and each building has one floor renovated, then the adsorption materials alone will cost at least 150 million.
Although the one in front of you is said to be the most expensive part of the entire equipment, other parts, especially such high-tech equipment, may not be that cheap.
Overall, if this project is carried out, it is roughly estimated to start at tens of billions.
This number is too big for him to make the decision alone.
Moreover, no benefits will be seen from this project in a short period of time. Strictly speaking, this is a public welfare project for people's livelihood.
Although Han Zizhen believed what the person in front of her said, carbon dioxide is a resource and can also be converted into starch, gasoline and other materials.
But overall, the main purpose of this project is to change the atmospheric environment of Jinling City and reduce the urban temperature.
Whether it's worth it or not, I'm afraid there's some quarrel with the city government this time.
Of course, although the investment is huge, if it can really be done, Jinling will undoubtedly become the most livable city in China, and it can even be said that there is no other city.
Because a suitable living climate is fatal to the attraction of ordinary people.
Who doesn't want to think that in summer, the temperature outside is still only 25 or 26 degrees Celsius?
This is to create a super city that is most suitable for human habitation.
Suddenly, a thought flashed through Director Han's mind.
